Some researchers use fMRI technology to study activity in the brain. The underlying activity detected by fMRI is by measuring the changes occurring in both oxygen amount present in the blood as well as the blood flow amount.
fMRI technology helps to detect the activity of the brain by measuring the changes occurring in both the amount of oxygen present in the blood as well as the amount of blood flow. This measurement is termed as the activity depending on the blood-oxygen level or called BOLD activity.
Functional magnetic resonance imaging or fMRI measures the activity of the brain by detecting various changes associated with the flow of blood. This technique will be relying on the fact of coupled activity of cerebral blood flow as well as neuronal activation. When an area of the brain is used up, there will be an increase in blood flow to that region.
The primary fMRI form uses contrast which is blood-oxygen-level dependent. This is a specialized brain type and a body scan that is used to map the activity of neurons in the brain or the spinal cord present in humans or in other animals by imaging the hemodynamic response which is related to the use of energy by the brain cells.
fMRI has come to dominate the mapping research of the brain as it does not involve injection uses, surgery, the ingestion of substances, and ionizing radiation exposure. This measure is usually corrupted by noise which is from various sources most frequently. Hence, the underlying signals are extracted by statistical procedures.
